Abstract
A method and equipment with a processing tool for the processing of carbon bodies, such as formation of holes in calcined carbon bodies, in particular nipple holes in anodes for use in electrolytic cells for the production of aluminium. The equipment comprises a positioning device (2) with means for positioning and fixing the calcined carbon element (1) and a processing station (8) with at least one spindle (10) which is designed to rotate and which has a processing tool (9) with one or more cutting elements (40-45). The spindle can rotate about a horizontal axis and can be moved in three directions which are perpendicular to one another so that the axis of rotation of the spindle can be given planetary motion during processing. The processing tool can be enclosed by a sheath which may have a suction device.
